Understanding Square Roots and Equations

This video tutorial, led by a special education virtual content specialist, covers an 8th-grade math lesson on the Pythagorean Theorem and irrational numbers. It includes guidance on using resources, instructional strategies, and engaging students with disabilities. The lesson focuses on reasoning about square roots, exploring rational approximations, and understanding equations with positive and negative solutions. Students are encouraged to use manipulatives and sentence starters to aid comprehension. Additional resources and practice problems are provided for further learning.
